To all whom at may concern:

Be it known that I, CHARLES A. DELON,

a citizen of the United States, residing at Canton, in the county ofStark and Stateof Ohio, have invented certain new and usefulImprovements in Vacuum-Cleaners, of which the followin is aspecification.

The invention rel including an electric motor, a suction tan and aseparating chamber communicatin with a plurality of inlet openingsadapted to communicate With the tubular shanks of.

suction nozzles. Such machines are designed and sold for the use of oneor two or some other particular number of suction nozzles at the sametime, and it desirable for practical reasons to construct the fan with agreater capacity than necessary to. create the proper suction in theshanks oi the particular number of nozzles which may be used; and it isalso desirable for economy to make the motor'with only a little greatercapacity thannecessary to create such sum tion. in, the operation ofthese machines dificulty has been experienced when more than theparticular number of inlet openings have been purposely or accidentallyused:

or opened at the same time, growing out of the fact that the work of thefan and the load on the motor will be so increased as to burn out themotor. This difliculty is over-' come by roviding a partitionbetweenthe', fan cham er and the inlet openings with an, orlfice thereinof. substantially the same a cross area as. the combined cross areas ofv the openings in the particular number of suction nozzles which -malimiting the amount of a11- which can be drawn into the fan to theamount of-air Wl'llCh may properly-be drawn through the shanks of suchparticular nozzles.

The invention thusdescribed, as embed-i .ied 111 a stationary vacuumcleaner, is illustrated in the accompanying drawings, forming' parthereof, inwhich- Figure 1 is a side. elevation of the vacuum cleaningmachine, with some parts broken away to show interior details; and :Fig.2,

REISSUED an elevation section of the electric motor, the fan blower andthe upper partof the separating chamber.

Similar numerals refer to sim lar parts throughout the drawings.

The machine includes the chamber .1 within the cylindric case 2, the fanchamber 3 within the blower case 4:, and the fan 5 located in the fanchamber and secured on the lower end of the spindle 6 of the electricmotor 7 which is secured on the blower case.

separating The inlet opening 8 of the collectingchamber is provided inthe cylindric case 2,

and communicates with the main conduit 9 which is preferably extendedinward or adjacent to the Wall of a building (not shown), and isprovided with a plurality of inlet openings 19 normally closed by thevalves 11, for use in cleaning the various apartmcnts of the building.One or more suction nozzle communicates with the collecting chamberthrough said conduit.

The cross area as at.:v-w of the opening in. the shank of each nozzleissuitably proportioned to the area of the opening of the inlet slot 12 ofthe nozzle to properly pernozzles, as 12, are provided, and the tubularform the work thereof, and substantially-the same size of openingprevails throughout the nozzle-shank, the tubular extensions thereof,and the communicating inlet opening. The cross area as at 3 of the mainconduit is preferably made much larger than the combined cross areas ofthe openings in the particular number of nozzle shanks designed to beoperated at one time, which enlargement is made forthe urpose of decreas theresistance and i i-iction caused by the ow of air through themain conduit,

the same being generally extended a 'con- F siderable distance from themachine to the various inlet openings. For the purpose of reducingfrictional resistance inthe fan' 5 at the speed adopted for operatingthe machine, the same is likewise made consider- 7 ably larger incapacity, that is, the peripheral outlet slot 16 is widened to make aconsiderably larger outlet area than the combined areas of theopeningsin the shanks of the particular number of nozzles to be used atthe same time; and thisslot is so widened for the further purpose offreely passing articles of refuse which may be drawn 1 through the fanand which would otherwise vacuumor suction in the tubular shanks of theparticular number of nozzles which may a, be properl used.

The or' ce 17 which constitutes the inlet to the fan chamber is providedin the part1t1on separating this chamber from the collecting-chamber,and, for the purpose of this invention, the cross area, as at zz, ofthis orifice, is made substantially equal to the combined cross areas ofthe openings of the particular number of nozzles designed to be used atone time; so that the 'fan can only take in the amount of air whichprop.- erly passes through the shanks of such articular number ofnozzles, and, there ore, the capacity'ofzthe motor cannot be overloadedto injure or to'burn it out.

I claim: 1. A vacuum cleaner including a separatng chamber having aplurality of valved inlet-openings communicating therewith, suctionnozzles having tubular shanks adapted to be connected with theinlet-openings, a suction fan having a capacity greater than that requred for the combined cross-areas of a partlcular numberof nozzle-shanks,a motor connected with the fan having a capaclty substantially equal tothe require ments of sald particular number of 'nozzlerating-chamber andthe fan having an orifice thereln with a cross-area substantially equalto the combined cross-areas of said particular number of nozzle-shanks.

2. A vacuum cleaner including a separat- -mg chamber having a pluralityof valved inlet-openings communicating therewith,

suction fan having a capacity greater than that required fior thecombined cross-areas of a particular. number of nozzle-shanks, a
